-Subject: [PATCH] Fix potential DoS issue with p2c header
-
-Unbounded p2c headers may be used to cause an application that accept
-PBES algorithms to spend alot of resources running PBKDF2 with a very
-high number of iterations.
-
-Clamp the default maximum to 16384 (double the default of 8192).
-An application that wants to use more iterations will have to chenge the
-jwa default max.
-
-Fixes CVE-2023-6681
